Haven't reported this yet as it so random, I've been trying to work out what's going on.

Following a recent upgrade, this MD suspends fine, but doesn't wake up.... 95% of the time. Sometimes, it does, eventually. One time, and I mean literally once, it started instantly as normal, and this is with me testing it a couple of times a day for the last few weeks. On the occasions where it has eventually woken up after a long time (maybe hours), I have tried to work out if a specific event was allowing it to happen (a quick reload, orbiter rebuild), but there's just no pattern that I can see whatsoever.

The fan always spins up and it all looks good, but nothing appears on the screen. I cannot ssh into it.
